Which of the following is TRUE?
to get hours from seconds you divide by 60
to get hours from seconds you multiply by 60
to get hours from seconds you divide by 3600
to get hours from seconds you multiply by 3600
Which of the following is NOT TRUE?
average speed is the same as constant speed
average speed cannot be higher than instantaneous speed
average speed is calculated by dividing the entire distance traveled by the entire time traveled
instantaneous speed is calculated by dividing the time it takes an object to pass by a specific point into the length of the object
An object that is at constant speed would have a speed vs. time graph that would look like/have the same trend as the objects graph for what?
time vs. distance with no slope
distance vs. time with no slope
distance vs. time with positive slope
time vs. distance with positive slope
If you conducted an experiment in which you used a car and ramp and moved ONE photogate to 4 positions along the ramp and recorded the object's time, which of the following is TRUE?
the graph of the data could be time vs. position of photogate
the graph of the data could be speed vs. time
the graph of the data could be speed vs. acceleration
the graph of the data could be acceleration vs. time
Which of the following is true regarding acceleration?
it is the change in speed divided by a specific distance
it is the change in speed divided by average speed
it is the distance divided by time for the end of a trip minus the distance divided by time for the beginning of a trip divided by time
none of these
Which of the following has the unit for the denominator squared?
position
distance
speed
acceleration
What would the patten/trend look like for an object that is accelerating on a distance vs. time graph?
a flat, horizontal line
a straight, positive slope
a straight, negative slope
a curved line moving up
Which of the following is true of a graph that is position vs. speed?
speed is the responding variable
speed is the manipulated variable
speed is constant
speed is the control
What does a straight, negative slope indicate?
on a distance vs. time graph it indicates that an object is moving in the opposite direction
on a speed vs. time graph it indicates that an object is moving in the opposite direction
in a distance vs. time graph it indicates that an object is slowing down
none of these
Which of the following is true of an experiment using a car and ramp with 2 photogates that are moved to 4 spots along the ramp while keeping the ramp in the same spot on the physics stand?
average speed can be calculated by using the width of the car and the time at any photogate
average speed can be calculated by using the distance the car travels along the ramp between the 2 photogates divided by the time between 2 photogates
instantaneous speed can be calculated by using the distance the car travels along the ramp divided by the time between 2 photogates
acceleration can not be calculated from the data gathered
